EXTENDING DREAMWEAVER CS4

Data sources

• The name property is the name of the server behavior that is associated with the data source, if one exists. It is a

required property. Some data sources, such as recordsets, are associated with server behaviors. When you create a

recordset and name it

rsAuthors, the name property must equal rsAuthors. Other data sources, such as session

variables, do not have a corresponding server behavior. Their name property must be the empty string (

"").

Note: A JavaScript class that defines these properties exists in the DataSourceClass.js file, which is located in the

Configuration/Shared/Common/Scripts folder.

inspectDynamicDataRef()

Availability

Dreamweaver UltraDev 1.

Description

This function determines the corresponding node in the data source tree from a dynamic data object. The

inspectDynamicDataRef() function takes the string that Dreamweaver passes in and compares it to the string that

generateDynamicDataRef() returns for each node in the tree. If a match is found, the inspectDynamicDataRef()

function indicates which node in the tree matches the passed-in string. The function identifies the node by using an

array that contains two elements. The first element is the name of the parent node, and the second element is the name

of the child node. If no match is found, the

inspectDynamicDataRef() function returns an empty array.

Each implementation of the inspectDynamicDataRef() function checks only for matches of its own object type. For

example, the recordset implementation of the

inspectDynamicDataRef() function finds a match only if the passed-

in string matches a recordset node in the tree.

Arguments

string

• The string argument is the dynamic data object.

Returns

Dreamweaver expects an array of two elements (parent name and child name) for the matched node; it returns a null

value if no matches are found.
